OIL-BURNING FURNACE.

Specification of Letters Patent.

Application filed March 7, 1910.

Patented Oct. 4, 1910.

Serial No. 547,741.

To all whom it may concern:

Be it known that I, L'Unwie Koozwanx, a subject of the Emperor of Germany, and resident of Prague-Kgl. Veinberge, AustriaHungary, have invented certain new and useful Improvements in Oil-l3urning Furnaces, of which the following is a specification.

This invention relates to an oil heating plant the object being to provide a plant of this kind comprising means allowing of the lighting of the fuel being easily carried out, of the gasification taking place in a lively and open manner, of the formation of soot being reduced, of the soot disengaged by the heating oil being burned and of the heat of the combustion gases being utilized in a more complete manner.

The accompanying drawing, given by way of example, shows one form of embodiment of the invention and in this drawing: Figure 1 shows a vertical longitudinal section of the oil heating plant; Fig. 2 shows a vertical cross section of same; Fig. 3 is a cross section of the oil burning vessel and F 4L shows a top plan view of same.

The easy lighting as well as the lively, open gasification of the heating oil are obtained by the fire proof, porous members 1 adapted to absorb the oil in the channels or troughs 2, of the burner 4E. The channels or troughs are spaced apart as at 3, for the upward passage of air for combustion. The fire proof porous members 1, are located in the channels and by capillary attraction absorb the oil, thus dividing it into fine particles, thereby making it more susceptible to ignition.

The formation of soot is reduced by the primary combustion air which enters through openings 6, is heated in channels 5 and is conveyed through openings 7 under the burning apparatus or burner t. This primary combustion air produces an increased heating of the applied bodies 1 sat urated with heating oil and consequently a still more lively gasification of the heavy hydrocarbons which easily produce soot. The soot which might still be formed during the process of combustion is decomposed by the heated secondary combustion air escapin g during the working of the plant through the openings 8,

The better utilization of the heat disengaged by the combustion gases is produced by the heat storing up device made in the shape of a grate work 11 of fire clay or the like material which is a bad conductor of heat. This heat storing up device yields after the fire has been stopped, to the heating body 10, the heat which it had absorbed or stored up during the combustion of the oil. The chimney or smoke escape flue 12 may be closed after the fire has been stopped, by means of a closing device 13, whereby the untimely escape of the heat stored up in the grate work 11 and the heating body 10 is prevented.

Having now fully described my said invention what I claim and desire to secure by Letters Patent, is 1 1. In an oil burning furnace the combination with an oil burner, of a plurality of spaced apart air heating channels surrounding the said oil burner and adapted to be heated by the latter, the said air channels extending transversely across the oil burner, discharge openings connected with said air heating channels and adapted to discharge the hot air as primary combustion air under the said oil burner and discharge openings provided in said air heating channels and adapted to discharge the hot air as sec ondary combustion air above the said oil burner into the flames produced by the latter, substantially as and for the purpose set forth.

2. In an oil burning furnace the combination with a casing, an oil burner therein comprising a plurality of spaced apart troughs which contain porous material, means for supplying the troughs with oil, a plurality of air ducts formed in the casing and which extend across the burner, the said ducts communicating with the atmosphere and terminating at one end under the burner to introduce air to the spaces be tween the troughs, and a checker work above the air ducts to retain the heat generated by the combustion of the oil atthe burner.

3. In an oil burning furnace, the combination with a casing, a burner therein, a hollow partition formed with an opening over which the burner is located, a series of spaced apart air ducts in the casing and communicating with the hollow partition under the burner and extending over the burner and communicating with the atmosphere below the plane of the hollow partition, a checker work in the casing above the ducts to retain the heat from the burner, and an exit. flue near the top of the casing.

4. In an oil burning furnace, the combination with a casing, a burner therein, a hollow partition formed with an opening over which the burner is located, a series of spaced apart air ducts in the casing and communicating with the hollow partition under the burner and extending over the burner and communicating with the atmosphere below the plane of the hollow partition, there being openings in the side walls of the ducts which communicate with the spaces between the latter, and checker work in the casing above the spaced ducts.

5. In an oil burning furnace, the combi nation with a casing, an oil burner therein,

said burner comprising a plurality of spaced apart troughs, porous members in said troughs, means for introducing heated air under the burner to pass upwardly between the troughs, checker work of porous fire proof material located above the burner to absorb the heat, an exit flue communicating with the casing near the top of the checker work and a damper for closing the flue.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
